ROOFING .ANDVSIDNG- CONSTRUCTO.,

Application filed January 2, 1925. l'Serial No. 260.

My invention relates kto improvements in Vroofing and siding construction and' mate rial for building purposes with more particular reference to prepared sheet surfacing material such `as asphalt shingles and asphalt yclap-boards and the objecty of the inventonis to devise an improved form of f this lmaterial by means of which a superior o construction may be obtained; a further object is to reduce the cost of erection' or applicationof kthe material to a building; a further object is tol enable the material to be applied without there being any exposed nails upon the outer surface thereof; a further object is to devise a construction in which a very good vshadow effect is obtained along the lower edges of the. sheets or strips of material; a further object is to provide a novel form of flush waterproof joint connecting abutting ends of adjoining strips of material; and a still further object is to devise material of this class which may be vequally applicable for use in' shingle form or in long strips for use as a clapboard, and which may also be equallyv applivcable for rooiing or siding purposes.

Other objects will appear in the course of the following specification.

My invention consists in the construction and arrangement, all as hereinafter more particularly described and illustrated in the accompanying drawings in which Fig. l vis a vertical section through a portion of a building showing the application of my invention thereto when used in the.

form of clap-board siding.

Fig. 2 is a face view lof the construction shown in Fig. l to a reduced scale.

Fig. 3 is ak fragmentary faceview of the adjoining ends of two adjacent strips of my clap-board the ends being slightly spaced apart. r

Fig. t is a section on the line l-t of Fig. 5 is a fragmentary face view ofr an improved waterproof joint used for con necting the abutting ends of twoadjacent stripskof my clap-board.

Fig. 6 is a perspective view of ak metallic clip used in my invention.

Fig. 7 is a detached perspective view of a comparatively thin piece of waterproof `material used in forming the waterproof joint shown in Fig. 5.

In the drawings, like characters of reference lindicate corresponding parts in the different views. f

In the form` illustrated, the Lapplication off. my invention to clap=board sidingV has been shown, although itis to be understood that my invention is equally"applicable in the form of shingles.y j (l lIn the form illustrated, l indicates the sideof a building ,which is surfaced or covered withlstrips offmy improved clapboard 2. j

The lower edge of each lstrip 2L is bent backwardly uponA the rear face of the kstrip at to form a groove L extending along the loweredge of the strip atv the rear thereof. The strips 2 are laid in parallelism upon the surface l which is covered in the ordinary manner of clap-board so that the lower edge 5 of each strip overlies the upperedge G of the adjacent strip.

L In laying .the strips, 'the upper edge 6 is secured direct to the surface l by nails 7 which nailsextend through the vupper ends i of metallic clips'S and the'uppe'r` edge of the .strip intothe surface l.

j The metallicv clips` 8 .are lspaced Vapart along Vthe upper edge of th'e'strip 2 and are formed from plates offset intermediately at@ so that the end portions l0 and l1 are disposed substantially in parallelism but are spaced apart.

vFrom an examination of Fig. l it will be apparent that, when the upper portion l0 of the clip has been secured-by the nail 7, the portion ll constitutes a downward-ly directed projection or linger which is spaced outwardly from the strip 2.

X'Vhen'the lowerniost strip 2 has been thus secured to the sliiface l along its upper edge 6, the next strip 2 is applied and in so doing the downwardly directed portion l1 of the clips 8 engage within the groove t along the bottom edge of this second strip and the upper edge 6 of this second strip is then secured to the surface l in the manner pre viously described, by nails 7.

The construction is then completed by Working upwardly applying the strips as described.

It will thus be observed that keach strip is secured directly along its upper'edge 6 tothe ysurface l and that thedovvnwardly directed clips S engage within the grooves 4A., and retain the lower edges of the strips in position.

. An improved feature of my invention rehr liz lee

A still further feature of the invention lies4 in the Vfact that due to the double thickness along the lower edges of the strips an eX- cept-ionally good shadow effect is obtained. This will be noted by the dotted line A A in Fig. 1.

In order to provide an` improved waterproof joint for connecting the abutting ends `of adjoining strips of material, I employ the construction illustrated in Figs. 3, 4, 5 and 7.

In this joint a comparatively thinv strip of waterproof material 12 is used.

The lower edge of this strip is bent backn wardly upon itself at 13 in the same manner asthe lower edges ofthe strips 2.

This piece 12l is cemented upon the rear face of one of-the'strips 2 so that a portion projects beyond the end of this strip 2 (see Fig. '3).

'Ihe two .abutting ends of the strips 2 are then brought together as in Fig. 5 andthe projecting portion of the piece 12 is cemented to the rear face of the other strip 2.

This construct-ion gives a very satisfactory waterproof joint, which enables the outer faces of the abutting strips 2 to be flush With 'each other and thus does not break the symmetry yof the exposed surface.

Vhile I have particularly illustrated `and described the application'of my invention in the form of clap-board siding, it may be equally well applied in the form of shingles and also for roofing.

Various modifications may be made in my invention wit-hout departing from the spirit thereof or the scope'of the claim and therefore the exact forms shown are to be taken as illustrative only and not in a limiting sense and I desire, that only such limitations shall be placed thereon as are imposed by the prior art or are specifically set forth in the appended claim.

What I claim as my invention is- In a building construction of the class described, tlie combination with a surface to be covered, of a plurality of sheets of covering material adapted to cover said surface, said sheets disposed in parallelism so that the lower edge of each sheet overlies the upper edge of the next adjacent sheet,

'each sheet having its lower marginal edge permanently bent backwardly upon therear face of the sheet to form an upwardly directed groove along that edge of the sheet,

lmetallic clips disposed in spaced relation along the upper edge of each sheet, nails eX- tendmg through said clips and the upper edge of the sheet and into the surface to be covered for securing said clips in position and also for securing the upper edge of the sheet to the surface, said clips formed with downwardly .directed outwardly offset portions engaging Within the aforesaid grooves for retaining the lower edges of the sheets in position.
